Answer:
Integers: is the set of all the numbers that can be created by adding ones or subtracting ones a given number of times to zero.
for example:
4 = 0 + 1 + 1+ 1 +1 is an integer.
-3 = 0 - 1 - 1- 1 is an integer.
0 is also an integer, you add ones zero times.
Then 5 examples of integers can be:
-10, -5, 0, 4, 18
Whole numbers: this set is the set of the positive integers and the zero.
Then 5 examples are:
0, 1, 4, 6, 173
Rational: All the numbers that can be written as a quotient of two integers.
5 examples are:
2/2, 7/3, 4/16, 100/10, -500/1048
Natural: Is the set of the positive integers.
5 examples are:
1, 4, 6, 120, 47
Irrational: Are numbers that have infinite digits after the decimal point, such that there is no pattern in those digits. The squareroots of prime numbers are always irrational numbers.
5 examples are:
pi, √2, √3, √5, √13
where pi = 3.141592653...
Is the relation between the perimeter of a circle and its diameter.
perimeter = diameter*pi.
